Original application filed September 80,-1915, Serial No. 58,264.Divided and this application filed July 10,

county of Montgomery, have invented certain new and useful Improvements,in Engine Startin Systems, of which the following is a ful clear, andexact description.

This invention relates to improvements in starting systems for internalcombustion or explosion engines, and more particularly to that type ofsystem which is adaptable for use with engines capable of operatingeither in a forward or reverse direction.

One of the objects of the present invention, is to rovidea startingsystem in combination with a reversible engine, which may be so coupledup to said engine .as to crank the engine in either a forward orreverse' direction, in accordance with the direction in which it ISdesired'to have the en ine run, after it has once been started.

6m manner of attaining the above object may be by providing two primemovers, one of which bein capable of operation in one direction -whi ethe other is capable of operation in the opposite direction,- and alsoproviding a luralityof connectingunits or devices which may be actuatedto couple prime m'overs to the ,engine, so as to operate the engine'ineither a forward or reverse direction.

In combination'with the above mentioned prime movers and their"respective connect-,

ing units, there is provided a controlling plurality of -o erative ingelement 1s moved to-one of its operative positions, one of saidprime'movers will be connected to the engine by means of one of theconnecting in one direction;

The functions of this controlling element, when moved to another of itsoperative po sitions, is substantially the same with respect to anotherprime mover. The result of the above arrangement and construction isthat when one of the prime movers is brought into operation, the enginemay be cranked in one direction, while when another of the prime moversis brought into units, to turn said: engine America,

operation, the engine will be cranked in an o posite direction.

The present-application is a division of my co-pending application, 30,1915,Serial Not-53,264.

In the present form of the invention, the

starting device includes separatemotors,

' one of which is mounted on each side of the engine, so that thisconnecting device may be readily shiftedto couple up that particularmotorto the .engine,-,to' crank the engine in one direction, while whenit is defiled September sired to crank the engine in an oppositedirectiore. another cranking device will be shifted into position tocouple another motor with. the engine, whereby the engine will becranked in an opposite direction. f

-By referring to the drawing, the starting device or system includes twoseparate prime movers or electric motors, designated by the numerals 120and 121,- one of which is mounted on each side of the engine.

In the present invention, of current is, employed as at 122, and hassuitable circuit connections with the respectifve motors, as will bedescribed hereina ter.

The main operating or controlling memher 123 is suitably mounted in sucha manner that it of operative positions, in any one of whic positionsthe circuit connections between the source 122 and one of the motorswill be closed concomitantly with the completion of the shifting of oneof the connecting units.

- By referring to the drawing, the operation of the system will bedescribed when the same is brought into operation by the shifting of thecontrolling member into the extreme right-hand positron.

Upon the initial movement of this controlling member, the connectingunit 124 will be moved toward the flywheel 125, and

concomitantly an initial movement will be imparted to the motor 120 bythe closing of the following circuit, through the, effect of abridgingelement 126, carried by the controlling member 123: from thebattery 122, conductors 127 and 128, through the series field winding129, across the brushesof the motor 120, through conductor 130 to thecommon terminal 131, across the may be moved to a pluralit*- a singlesource 128,. through theoppos te side of the battery, via conductor 134?i v The object of imparting a'n'initial movement to the motor, in theconnecting up of the pinion of the connecting unit with the flywheelgearing.

Now, as soon as the pinion 124: has been brought into enmeslnnent withthe flywheel gearing a determined degree, the controlling memberclosethe following circuit, which may be designated the main crankingmotor circuit: from the battery .122, conductors-127 and series fieldwinding 129, across the brushes of the motor 120 to lead wire '130, a.common termmal 131', through the bridging element -126--to1 the terminal135 and thence back to the battery, via con- -duetor"134. -VVhentheengine has become self-o erative, the controlling member 123 may:'released, and the spring 136 will effect the unmeshinglmovement of gear124, and will restore t emember 123 to inoperative position. I v

,If it is .desiredto crank the engine in a directionopposite to thatresulting connecting the motor I 120 therewith, the main controllinglever 123 ,should be shifted to its extreme left-hand nperativeposition, in whichcase .the motor 121 will be conneeted up to theflywheel gearing, and a substantially duplicate set of circuitconnections will be so eflt'ected as to give the required operations tothe motor. Spring 137 will be effective, upon the release of memher.123, to disconnect the motor 121 from the fly-wheel, and to restoremember 123 torlnoper'ative osition. I x While the 'orm of mechanism.herein shown and described constitutes a preferred formof embodiment oftheorinvention, it is to be understood that other forms might beadopted, all coming within the scope of the claims which follow.

-What I claim is as follows:
